Safety guard lock switch

article image Enhancements available.

THE 3SE28 family of safety limit switches from Siemens Automation & Drives is suitable for guard door monitoring where personnel entry must be prevented by a locking mechanism.

Distributed by Ramelec , the 2000N lock is complemented by a selection of separate actuators.

Further enhancements include auxiliary releases (with or without key locks) for entry to guarded areas during power outages. Status LEDs on the switch are included on some models. 24V dc, 110V ac and 240V ac versions are available.

The 3SE28 units provide a heavy-duty alternative to the successful 1200N locking units 3SE37/8 from Siemens.
